Inflammatory Bowel Disease (IBD) describes disorders where the lining of the digestive tract is inflamed. There are two types of IBD disorders: ulcerative colitis, where the large intestine and the rectum are prone to inflammation and sores, and Crohn’s disease, which usually affects the small intestine.
Researchers have reported diet, age, family history, cigarette smoking, and certain medications, among other factors, as being responsible for causing or worsening IBD.
They have also said changing diet patterns can help explain changing patterns of the prevalence of IBD. For example, a 2023 study in The Lancet attributed a higher incidence of IBD in rural Telangana to the greater availability and consumption of processed foods.
